Towards a generic rotation of the Haar-Like features

摘要

The idea of this paper is based on three key points: The first is to propose a method allowing finding possible angles to rotate a Haar-Like feature without destroy its sides. The tangent of each angle equal to an rational number i.e. each angle equal to acrtan(Y/X) where Y and X are integers. The second point is manifested by the use of this rational number to determine the pixels forming the sides of the feature. In the latter, we present the integral image of a Haar-Like Features based on the work already done.
